Near-total lunar eclipse is coming up with the Americas in prime position

Astronauts aboard NASA’s uncrewed Artemis I mission in 2022 were protected from nearly half the radiation they would have otherwise encountered during a solar storm, thanks to a prototype radiation-shielding vest tested on a mannequin named Zohar, according to research published in Nature on 20 August 2026. The experiment involved attaching a specially designed vest to Zohar, a humanoid mannequin used to simulate human presence during the flight. The vest was equipped with materials capable of absorbing high-energy particles emitted during solar flares. During the mission, Zohar was exposed to simulated conditions akin to those experienced during a severe solar storm, allowing researchers to measure how effectively the vest mitigated radiation exposure. The findings suggest that such vests could significantly reduce the risk of radiation-induced health problems for astronauts traveling beyond Earth’s magnetic field, particularly during long-duration missions to the Moon or Mars. Radiation exposure is one of the greatest risks for spacefarers, as it can lead to cancer, neurological damage, and other serious illnesses. The study marks a key step toward developing safer gear for future crewed missions. The vest, developed by a team of scientists and engineers, uses advanced composite materials known for their ability to block cosmic rays and gamma radiation. These materials are lightweight enough to be worn under standard astronaut suits while still providing substantial protection. The design was inspired by previous experiments conducted on the International Space Station, where similar shielding techniques were tested for their effectiveness in reducing radiation levels inside confined spaces. Zohar’s journey aboard Artemis I was part of a broader effort to understand the challenges of long-term space travel. The mission, launched in November 2022, was the first in a series of planned lunar explorations aimed at paving the way for human return to the Moon. During its 25-day flight around the Moon, Zohar’s data helped researchers assess the performance of various technologies under real-world conditions. The results of the study are expected to inform the development of more robust safety protocols for future missions. NASA has already begun discussions with private aerospace companies to integrate the technology into upcoming spacecraft. Researchers emphasize that while the vest offers considerable protection, it is not a complete solution. Additional measures, such as improved spacecraft shielding and optimized mission planning, will still be necessary to ensure astronaut safety. The research team includes experts from multiple institutions, including NASA’s Johnson Space Center and the German Aerospace Centre (DLR). Their collaboration highlights the growing international cooperation in advancing space exploration and ensuring the well-being of those who venture beyond Earth. The study also builds on decades of research into radiation protection, with recent breakthroughs focusing on both passive shielding and active mitigation strategies.
